One time, to get it out of her system, right?

You shiver as you climb onto the bed next to her, still fully clothed, in contrast to her own near-nudity.
"W...we're agreed, right? This is a one time thing, baby girl. Get it out of your system." You aren't sure if you're trying to convince yourself or her.
"Sure, daddy..." her eyes are mischievous and hungry. She lays next to you, propped on an elbow, sipping her bubbly drink before leaning back to set it on the other end table. the stretch shows off her tight, appealing torso and perky tits, and you can't stop yourself from letting your fingers trail from her stomach to her hips. She laughs, giving you a kiss that tastes of the wine. "Just relax, let your mind go, James." She slides a hand down the front of your waistband, kissing you some more. When her fingers close around your cock, you involuntarily take her advice as your conscious, moral mind starts to fade away, and your lizard brain asserts itself.
"Mm...." you moan softly into her mouth.
"You're getting stiff so quickly." she whispers in your ear. "Am I really that hot?"
"......yes, baby. Smoking hot." It's not a lie. She is smoking hot. She's a tiger and a pussycat and a tempting succubus and your precious angel, all rolled into one.
"Let me get you all ready, James..." she deftly frees your stiffening member from the confines of your shorts and boxers, tugging them downward. With love and lust co-mingled, she begins to kiss, lick, and moisten the tip and shaft, all the while rubbing your balls with her hand. You stroke her hair, and run a hand down her bare back.
"I'm sorry, baby. I'm sure I'm all sweaty from golf. I should have showered..."
Riley, turns to smile at you, cutely putting your dick between you and her and kissing the sensitive underside of the shaft.
"I don't mind, da- James... It tastes fine."
